A word from Ann, the 'Cabbage Patch Doll' costume creator:

My daughter was almost a year old and she was hardly walking. We needed something to take her trick or treating in so we decided to decorate her stroller. We just used a regular box and cut it out and spray painted it yellow. I used green duck tape for the edges and then made a fake birth certificate. We used stickers to decorate the box and cellophane for the front. I dressed her in regular clothes like a cabbage patch doll but in overalls. We had a yarn hat made so it would look like a doll. Then we just placed green material over her stroller and secured the box over her so we could push her around!
